Mu musaruro w’inganda, imiyoboro imeze nk '“imiyoboro y'amaraso” ihora itwara ibikoresho nk'amabuye y'agaciro, ifu y'amakara, n'ibisigazwa by'imyanda. Nyamara, ibyinshi muribi bikoresho bifite ibiranga ubukana bwinshi nigipimo cyihuta. Imiyoboro isanzwe izahita ishira hamwe no kumeneka, bidasaba gusa guhagarika no gusimburwa kenshi, ariko birashobora no guhungabanya umutekano kubera kumeneka kw'ibintu. Kugaragara kwa silicon karbide imiyoboro idashobora kwihanganira ni ugukemura "ikibazo cyo kwambara".
Abantu bamwe barashobora kubaza, ni ubuhe bwoko bwa "carbide silicon"? Mubyukuri, ntabwo arikintu gishya. Mu byingenzi, ni ibintu bidasanzwe bidafite ubutare bugizwe na silicon na karubone, hamwe nubukomezi bwa kabiri nyuma ya diyama na corundum. Byinshi murwego rwohejuru rwumusenyi nibikoresho byo gusya bikoreshwa mubuzima bwa buri munsi bakoresha karubide ya silicon. Iyo ibi bikoresho bikomeye cyane bikozwe murukuta rwimbere rwumuyoboro, ni nko gushyira urwego rw "intwaro za diyama" kumuyoboro. Iyo uhuye nibikoresho byambaye cyane, birashobora kurwanya byimazeyo ingaruka no guterana kwibikoresho, bikongerera cyane igihe cyumurimo wumuyoboro.
Ugereranije n'imiyoboro gakondo, ibyiza bya silicon karbide imiyoboro idashobora kwambara birenze "kwambara nabi". Imiyoboro isanzwe yicyuma irashobora kwangirika byoroshye nibikoresho byangirika mugihe cyo gutwara, kandi imiyoboro ya pulasitike iragoye kwihanganira ubushyuhe bwinshi nigitutu. Nyamara, ibikoresho bya karubide ya silicon ubwabyo bifite ibiranga aside irwanya alkali hamwe nubushyuhe bwo hejuru. Haba gutwara acide acide cyangwa ifu yamakara yubushyuhe bwo hejuru, birashobora gukora neza nta mpungenge zikunze kugaragara kuri "ruswa yo gutobora" cyangwa "ihindagurika ryubushyuhe bwo hejuru". Icy'ingenzi cyane, urukuta rwarwo rworoshye, bigatuma bidakunda kwirundanyirizwa hamwe no guhagarara mugihe cyo gutwara ibintu, kugabanya ibibazo byo gusukura imiyoboro no gukomeza umusaruro.
Muri iki gihe, mu nganda nko mu bucukuzi bw'amabuye y'agaciro, amashanyarazi, ndetse n’ubuhanga mu bya shimi bisaba kwihanganira kwambara cyane ku miyoboro, imiyoboro ya kariside ya silikoni irwanya imyenda yagiye isimbuza buhoro buhoro imiyoboro gakondo. Ntabwo ikeneye gusimburwa buri mezi atandatu nkimiyoboro isanzwe, ntanubwo bisaba amafaranga yo kubungabunga inshuro nyinshi. Nubwo ishoramari ryambere rishobora gusa nkaho riri hejuru gato, mubyukuri bifasha uruganda kuzigama amafaranga menshi mugihe kirekire. Ku bigo bikurikirana umusaruro unoze kandi uhamye, guhitamo imiyoboro ya silicon karbide idashobora kwihanganira ni uguhitamo igisubizo cyubwikorezi "guhangayikishwa cyane, kuramba".
Hamwe nogukenera ibikoresho biramba hamwe numutekano mukubyara inganda, ibintu byo gukoresha imiyoboro ya silicon karbide imiyoboro idashobora kwangirika ihora yaguka. Ikemura ikibazo "gishaje kandi kigoye" mu bwikorezi bwo mu nganda hamwe n’imikorere ikomeye yibikoresho ubwabyo, kandi inatanga imishinga myinshi ihitamo neza mu nzira yo kugabanya ibiciro no kuzamura imikorere.
